How the numbers stack up against the price
£1.15 buys 25g of protein here, which makes it the 11th cheapest of the 24 powders we have reviewed, behind Scitec Nutrition 100% Whey Protein Professional at £1.11, and 5p over the median.
It is a genuine single-source isolate at 87g of protein per 100g with 0.4g of sugar, so it does the job an isolate is bought for. Note that it shares a brand but nothing else with PER4M Whey Protein, which is a four-source blend with 25 times the sugar.

Cheapest in-stock listing at a partner retailer, for packs of 400g and over. MyProtein Clear Whey Protein, Protein Works Vegan Protein 360 - GOLD Innovation, Protein Works Vegan Protein 360 - PLATINUM Innovation, Protein Works Vegan Pea Protein - BLACK Innovation, Protein Works 100% Micellar Casein - BLACK Innovation, Protein Works Diet Whey Protein Isolate - BLACK Innovation, Protein Works Clear Diet Whey Protein - GOLD Innovation have no partner listing in stock, so they carry no figure.
A single protein source with no concentrate and no hydrolysate. This is the same brand as PER4M Whey Protein but a completely different formula, without the skim milk powder that drives that product’s sugar content.
What the label gets right, and wrong
Strengths
- One of the most widely stocked isolates in the UK
- 87g of protein per 100g from a single isolate source
- 0.4g of sugar and 1g of carbohydrate per 100g
- Twenty-one flavours, which is a wide range for an isolate
Watch-outs
- PER4M’s own product pages disagree on whether a serving is 26g or 27g of protein
- No evidence of Informed Sport or Informed Choice certification
- We found no independent review of this product at all, so there is nothing on taste or mixability we can pass on
- Country of manufacture is not disclosed
Where to buy it
Ordered by cost per 25g of protein, because pack sizes and protein densities differ enough that a headline price on its own does not tell you which is better value.

Price history
What a scoop actually contains
Taken from the manufacturer’s published label. Source.
PER4M’s own pages are inconsistent on the serving figure: its White Chocolate page says 26g of protein per 30g scoop and its Vanilla Creme page says 27g. The full per-100g panel comes from a retailer reproduction rather than from PER4M.

Third-party testing
Certification is per programme and often per flavour or per batch, so a badge on one product does not carry across a brand’s whole range.
No entry found in either database.
Made by
PER4M, founded 2011, merged with Hatch 19 in 2018, offices in the UK and ItalyPER4M does not disclose the country of manufacture.
What the maker does not publish
- PER4M’s own pages give two different per-serving protein figures.
- No independent review of Isolate Zero exists that we could find. Do not assume PER4M Whey Protein’s flavour reputation carries over, since it is a different formula.
- Country of manufacture is not disclosed.
Questions buyers ask
